Image Won't Load

I spent HOURS today creating this brochure. I had to move some elements to account for the bleed lines. On the very LAST step, I went to move one image over. The image disappeared and now it won't let me upload any image in its place. I spent all day frustrated over how slow and unresponsive Adobe Express was, but tolerated it because my brochure was being completed. To be on the very LAST step and the program to fail me, I cannot even explain my frustration. This program was working fine before this worthless update.
